ok, i have a 300zx that im trying to bleed the clutch in... and i cant do it. yesturday i did it in a 240sx in like 5min. but this stupid zx wont do it, i bleed it untill there is no air, but the pedal still doesnt pop bakc up, when i pump it a lil it comes up, but then i lit go of the pedal all the fluid comes up throught the master cylinder. could it be sucking air somewhere in the line? i got a new clutch cyliner and new master cylinder still dont work...
